This paper examines the number of stops
made by individuals during their evening
commute. The paper applies a methodological framework that relates stop-making to relevant
individual, land-use, and work-related ...

This paper jointly examines the length between successive participations in several activity purposes using a 1999 multi-week travel survey conducted in the German cities of Halle and Karlsruhe. A multivariate hazard model ...

On 9 June 2009, an M-bLg 2.8 earthquake shook Cleburne, Texas, a community not known to have previously experienced earthquakes. Over 50 small earthquakes followed by the end of December 2009. A temporary network of four ...

This paper examines the out-of-home, weekend, time-use patterns of children aged 5 through 17 years, with a specific emphasis on their physical activity participation. The impact of several types of factors, including ...

Recent advances in global positioning systems (GPS) technology have resulted in a transition in
household travel survey methods to test the use of GPS units to record travel details, followed by
the application of an ...

This paper examines the use and travel impacts of two forms of Information and Communication
Technologies (ICTs): mobile telephones and computers. The travel impacts are examined in the
context of participation in ...

This paper examines the discretionary time-use of children, including the social context of children's participations. Specifically, the paper examines participation and time investment in in-home leisure as well as five ...

Travel mode and departure time choice of urban trips are important determinants of urban travel
demand and the temporal distribution of this demand. While mode choice has received substantial
attention in travel demand ...

The purpose of this study is to examine the spatial and temporal characteristics of weekend work episodes. Specifically, we examine whether individuals work over the weekend and, if they work, whether they work at home or ...

Activity-travel behavior research has hitherto focused on the modeling and understanding of daily time use and activity patterns and resulting travel demand. In this particular paper, an analysis and modeling of weekly ...

Self-injection of background electrons in plasma wakefield accelerators in the highly nonlinear bubble regime is analyzed using particle-in-cell and semi-analytic modeling. It is shown that the return current in the bubble ...

We present fits of generalized semi-analytic supernova (SN) light curve (LC) models for a variety of power inputs including Ni-56 and Co-56 radioactive decay, magnetar spin-down, and forward and reverse shock heating due ...

In human cells, DNA double-strand breaks are repaired primarily by the non-homologous end joining (NHEJ) pathway. Given their critical nature, we expected NHEJ proteins to be evolutionarily conserved, with relatively little ...

The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This implies that small, including ...

Switching by parasites to novel hosts has profound effects on ecological and evolutionary disease dynamics. Switching requires that parasites are able to establish contact with novel hosts and to overcome host defenses. ...

A growing number of galaxy clusters at z = 1-2 is being discovered as part of deep optical, IR, X-ray, and Sunyaev-Zel'dovich effect surveys. For a complete picture of cluster formation, however, it is important that we ...
